Mobile crushing plant for construction waste away from the city

China in recent years both in the broken theory, broken technology, architecture, design and equipment manufacturing, has a lot of progress, but have to admit that compared to broken machinery with foreign, there are still some gaps.The structural design of the crusher, for example.Late in the foreign countries from the last century began to use computer simulation technology to optimize the the crusher institutions, chamber type, yield and wear, thus greatly improving the performance of the crusher, to shorten the product development cycle, improve the competitiveness of products in the market.However, domestic Simulation and Optimization of the crusher is mainly limited to specific types of crushers to prepare the corresponding program to optimize the design of these programs are mostly poor reusability, can only solve specific problems in specific models.There are also scientists began to try advanced kinematics and dynamics simulation design tool for rapid development of the crusher, simulation and optimization design of mechanical design parameters, which greatly reduces the workload of the simulation design, shorten product development cycle to improve the simulation model reuse.To bridge this gap, to catch up with the same period in the international cement, which is still a long process.Compound pendulum jaw crusher manufacturing as an example.Of compound pendulum jaw crusher movement method of the four-bar linkage mechanical design theory has made great progress, approaching the international level over the same period.Bidirectional nip angle of the compound pendulum jaw crusher crushing chamber, the short bracket put on a large angle, to reduce the transmission angle and eccentricity, the products are often provided by foreign companies has proven advanced design theory to improve product performance and reliability.China's domestic manufacturers due to various brick making machine reasons advanced design theory rarely before the 1970s, almost all of the 20th century stereotypes of the mainstream products, wear-resistant material (such as high manganese steel) and an important component parts (such as aligning roller bearings domestic infrastructure)., life below the international advanced level of similar products.In addition, OEM processing and assembly process also has a larger gap with foreign Reason for the gap at home and abroad, these reasons are not "theories and techniques behind general.Market demand for objective reasons we can not be avoided.Broken equipment manufacturers to focus on the international Mobile Crusher market in the U.S. and Europe, its market required crushing equipment specifications and a high degree of automation, and mobile.

China is in the large-scale capital construction period, just launched faster, less investment, and a tight market is a direct result of shoddy, low levels of technology and jaw Crusher high energy consumption and serious pollution of the environment have entered.Objective reasons not to make up for a short period of time, but the technology gap alicey599 through technology introduction, digestion and absorption, independent innovation, and rapid high-end mobile crushing industry to the world.While this "binge eating" approach allows us a short period of time can weight on several kilograms, but this is not a long-term policy.We should be in a good light "copied" the process, learn to others, advanced research methods and the unique and innovative ideas.For example, abroad an innovative idea - "the materials on behalf of timber," is the value of learning.The crusher is a wear-resistant material consumption equipment.Reduce the consumption of wear-resistant materials for many people in the industry research topic.Improve the performance of wear resistant material is a method to reduce the wear-resistant materials, but blindly only to improve the performance of wear resistant material, after all, rock Crusher is a dead end, does not fundamentally solve the problem of wear-resistant material consumption.The foreign idea is to reduce the wear-resistant materials consumed to the generation of wear resistant material way to the material.This practice in foreign countries has been put into the initial stage.Abroad vertical shaft impact crusher with the material feed pad to replace the liner as wearing parts (part design material pad protection, canceled expensive chrome alloy steel surfacing), this is a good example.The gap is there, After years efforts, China in broken field has also made substantial progress.[brick making machine:http://www.xbm-aac.com] "The original shock absorber in the major cement production line supporting equipment development and application of engineering projects and the hydraulic system and flexible hydrophobic technology in the tooth roller crusher use of its technical indicators have reached international advanced level .This fully shows the good performance and innovation capability of independent innovation made.
